You became my favorite person in the world. I was really stressed out because a couldn’t calculate the chisq to a result of an investigation, but you explained super clear and finally i can finish my project. Thank you so much!!!

A video from 2 years ago SAVED MY LIFE!!! Thank you for such a great explanation!!!

you just got cited in my lab report since I used your methods in my methodology and results section for my results, thank you.

Thank you for this. As someone who hasn’t done stats for 20years this was by far the easiest to follow explanation I have found.

I want you to know that this video literally saved my day. I have to take a poster to a conference and I kept getting recommended using one-way ANOVA, which gave me very silly results for my binomial data set. Thank you very much friend

This is amazing. thank you so much. i had a statistics assignment i was to solve within a couple of hours, but this 8 minute video saved me. keep doing what u do.

Oh my, this helped me SOOOOO much!!! Thank you!!

Easiest video on chi square. great job.

You are truly amazing ... I was tensed due to details mentioned in literature and now uou made it soo simple and easy to implement... wow love your work

Thank you! This is so much easier and so much clearer than any of the others!

Thank you so much, i was so stressed and did not find anything helpful until i came across your video. You saved me and my thesis, I can not thank you enough😓❤❤

Thank you so much for this video. I suck at statistics and Ive got a paper due tomorrow and this has helped me solve a data set in under 2 hours compared to the over 6 hours it took to solve a different data set yesterday :)

Very much appreciated. This helped me cut down 3 hours of hand work down to 30 minutes of excel. You are a life saver. Now if i can just get my group to contribute with our work it will be even less time consuming LOL.

WELL EXPLAINED

Thank you so much you saved me for my test

thank you, you save my test

Great content

Hi Steve Thanks so much for your video - really useful. However, how do I do the Chi square test for proportions with more than one categorical group. For example, I ask 3 cohorts (healthy, anxious and depressed) if they smoke (yes/no)? Thanks in advance

Thank you so much. Can we apply it if the total sample number is 25? Thank you, I really appreciate it.

Thank you for this. You just saved my life literally😂

You are a legend sir Thank you

Super tutorial Sir

So simple and easy to follow, thank you!

Good job for students, thanks very much

Thank you, How can we test it for a single variable?

Excellent 👍👍👍

thank youuuuuuuuuuuuuuuuuuuu for this

can you do one of these with one row and two columns

THANK YOU VERY MUUUCCCHHHHHHHH

Can the interdependence of the categories be established simply by using the Observed values and not using Expected values?

how to do it in r without built-in func?

i have a 2-way table with some zeroes in the data set, i cannot find the chi square test in many calculators , can you help? @top tip bio

bless you king

Can I use this method with multiple choice questions?

is there a calculator which has the chi-square function but which is non-programmable? because in the exam I am not allowed to have a programmable calculator.

Legend!

Nice

is it also applicable when you have, instead of female and male, you have three ages (examples are 18-19,20-21,22-23)?

Its very helpful. Thanks. What means if P-value is zero?

@seco9349

It van never be zero, as there is always the smallest probability that it might actually happen

Hi, I was curious why you did not have to use the Chi-Square possibilities table in order to determine if you reject the null hypothesis? Why did you default to alpha 0.05?

@lmoore9524

Жыл бұрын

.05 is the most common convention and means there is only 1 chance in 20 this result happened by chance. You could choose .01 for a more strict test of 1 in a 100 chance or .10 for 10 out of 100 to be less strict in ruling out the null assumption.

thanks sir

Nice ❤️ ❤️ ❤️

is it association of gender to smoking or the unequal distribution of gender between the groups? Can we say that both groups have unequal sample distribution for each sex? What i mean is can i have test for gender distribution between both groups?

fine

Sir, I have a doubt. you have done for 2*2variables..Can we do it for 3*3 variables..Is it correct to do chisquare test for 3*3 variables

how do i find my alpha level??

why am i getting 2 different p-values when I use CHISQ.DIST.RT vs CHISQ.TEST

@ogechichilaka6294

I noticed same. I think CHISQ.TEST works for only 2×2 table

@amarpratap8785

​@@ogechichilaka6294I got different results for even 2×2 table

Clutch

The values of p are like 0.7,0.8 , 0.8 , 0.4 etc Is this a problem . Because i knoe is should be less than 0.05

If we can accept or reject the null hypothesis based on the chi-square value alone, then why is there a need to derive the P value from it. Why an extra step?

@naveenshaji9020

Actually you can only reject or fail to reject null hypothesis.

It displaying a syntax error message

According to you, the Null hypothesis will be accepted if P > 0.05 and rejected when P < 0.05. This is opposite to what this gentleman is stating. Which one is correct? kzread.info/dash/bejne/iYyEpNF_dNS0hs4.html
